NetworkingKubernetes supports for Third-party netwroking the cluster via the MLM plugin. For more infromation, please see Cluster Networking.According to this Chinese blog, Principles and Solutions of Kubernetes Networking from Yourongyun the three top of the MLM Pro Viders for kubernetes cluster based on VMs is Project Calico, flannel, Weave Net.And also, here is comparison of variable networking solution

Kubernetes ArchitectureThe overall architecture of the kubernetes is as follows:Master is the main control node, which runs Apiserver,scheduler,controller-manager and other components. Minion is the equivalent of a working node, which runs Kubelet,proxy,cadvisor and the most important Docker components. Here's how to actually deploy this cluster management tool.EnvironmentYy1 10.193.6.35Yy2 10.193.6.36Yy1 a

During the Ming Dynasty, Emperor Chengzu Zhu Di, in order to develop overseas trade and establish his prestige, sent Zheng He seven voyages, set the ancient China's largest, the most ships (more than 240 ships), the most seafarers (27,000 people), the longest time, than the European countries sailing time of half a century earlier ocean voyage feat.

k8s Basic Concepts1. NodeNode as a working node in the cluster, running a real application, the smallest running unit kubernetes managed on node is the pod. Node runs Kubernetes's kubelet, Kube-proxy service processes, which are responsible for pod creation, startup, monitoring, restart, destruction, and load balancing for software patterns. The information that node contains: node address: The IP address of the host, or node ID. node op

First, the Environment preparation1. Installing the configuration Docker The v1.11.0 version is recommended for use with Docker v17.03,v1.11,v1.12,v1.13, which may not work properly with the later version of Docker. #移除以前安装的docker，并安装指定的版本[[emailprotected] ~]# yum remove -y docker-ce docker-ce-selinux container-selinux[[emailprotected] ~]# rm -rf /var/lib/docker[[emailprotected] ~]# yum install -y --setopt=obsoletes=0 docker-ce-17.03.1.ce-1.el7.

What is a container?Kubernetes is a container management platform. It is conceivable that we need containers to manage them. But what is a container? The best answers to the official Docker documentation are: A container image is a lightweight, standalone, executable package that contains everything that can be run: Code, runtime, System tools, system libraries, settings. For Linux and Windows-based applications, containerized software can ru

Kubernetes introduced Kubeadm from 1.3 to try to simplify its complex installation. But Kubeadm is still not stable, and I personally think Kubeadm instead of trouble, rather than directly with the script or other automated tools to install the neat. There are also alternatives to HA for KUBEADM configuration master, such as using highly available cluster software such as keepalived or Corosync. So in this document, I will still use the traditional wa

ClusterCluster is a collection of compute, storage, and network resources, and Kubernetes uses these resources to run various container-based applicationsMasterMaster is the brain of cluster, whose primary responsibility is scheduling, that is, deciding where the application will run. Master runs the Linux operating system, which can be either a physical machine or a virtual machine. To achieve high availability, you can run multiple master.NodeNode's

I. Background INTRODUCTION As we all know, due to the domestic network reasons, in the construction of kubernetes environment, often encountered the need for the mirror can not find the situation. After all, it is not a good idea to pick up rubbish in Dockerhub, this article teaches everyone to build their own mirror warehouse in Dockerhub.
